Key Components
Main Components
Fan Casing
With structural stability as top priority, Maxwatt's fan casings are engineered to withstand operational stresses, ensuring stable and reliable performance without distortion or fluid leakage.
Designed for easy assembly and maintenance access, the casing simplifies routine inspection and repair, complete with strategically located inspection ports for rapid impeller evaluation.
Casing Design Analysis
The volute casing plays a critical role in kinetic pressure recovery and energy loss minimization.
All casings undergo Finite Element Analysis (FEA) to verify structural integrity, while Computational Fluid Dynamics (CFD) simulations optimize aerodynamic flow performance.
Material Selection
Materials are meticulously selected based on specific MVR operating environments, including:
- Carbon Steel / Stainless Steel SS304, SS316L, SS316Ti / Duplex & Super Duplex Steels
Each material is thoroughly verified through accredited laboratory testing to ensure chemical and physical properties strictly conform to design specifications.
Fan Impeller
Maxwatt impellers are manufactured using state-of-the-art technologies optimized according to flow rate categories.
- Low-capacity impellers are typically manufactured via 3D Metal Printing (Additive Manufacturing),
- High-capacity impellers are fabricated using high-precision CNC Machining.
Blade profiles are also tailored according to aerodynamic flow requirements:
- 2D profiles are applied to high-capacity impellers,
- 3D profiles are utilized for low-capacity impellers.
Blade geometry, curvature, blade count, and angles are meticulously calculated to maximize compression efficiency while minimizing aerodynamic losses (turbulence and flow separation).
We continually advance compressor performance and energy efficiency by simulating flow patterns and fine-tuning blade contours through rigorous Computational Fluid Dynamics (CFD).
Material Selection
Impeller materials are rigorously chosen based on specific application demands, focusing on superior mechanical properties and corrosion resistance. Commonly utilized alloys include:
- SS304 / SS316L / SS316Ti / 17-4 PH Stainless Steel
- Duplex & Super Duplex Steels / Titanium Alloys
Throughout the manufacturing process, strict material inspections ensure no flaws or imperfections compromise structural integrity. Non-destructive testing (NDT), including Ultrasonic Testing (UT) and Dye Penetrant Testing (PT), thoroughly verifies impeller structural soundness.

Stress Analysis
Utilizing Finite Element Analysis (FEA), we thoroughly evaluate stress distribution and deformation under all operational and transient load conditions.
This analysis effectively identifies stress concentrations and potential fatigue zones, enabling structural optimization of the impeller to ensure unmatched reliability and safety.
Balancing & Rotor Dynamics Analysis
Every impeller undergoes high-precision Dynamic Balancing for smooth, vibration-free operation, accompanied by comprehensive rotordynamic analysis of the rotating assembly.
This accurately determines critical speeds, ensuring operating speed ranges remain well clear of resonance margins to guarantee operational stability and peak energy efficiency.
This core technology proactively eliminates the risks of resonance, excessive vibration, and premature fatigue failure in high-speed rotating machinery.
Gland Seals
Our gland seals feature an innovative floating seal design incorporating precision-engineered carbon rings.
Arranged within the seal housing, sealing performance is enhanced by strategically placed buffer fluid ports. Using low-pressure steam or treated water as buffer fluid maintains stable housing pressures, maximizing sealing efficiency and dependability.
This delivers zero external leakage, outstanding durability, and ease of maintenance even under challenging high-temperature and high-pressure conditions.
Bearings
Maxwatt rotating equipment primarily incorporates heavy-duty rolling element bearings, with options for oil bath or pressurized oil lubrication systems depending on duty specifications.
For precise and stable lubrication, each package includes a self-contained lubrication system, ensuring uninterrupted lubrication delivery and easy servicing.
The bearing arrangement supports the rotor shaft on a rigid pedestal, with bearing assemblies positioned to support the shaft while the overhung impeller mounts directly on the opposite end. This maximizes dynamic stability, suppresses vibration, and maintains precision durability during high-speed continuous operation.

MVR Systems & Industrial Applications
In an era where ESG and decarbonization are paramount, DM HITECH's MVR solutions recover waste low-pressure vapor and recycle thermal energy—offering the ultimate pathway to industrial energy conservation.
Core Strategy for ESG Management
Conventional thermal processes waste immense amounts of energy when steam undergoes phase changes, releasing approx. 540 kcal/kg of latent heat. MVR compresses and recycles this latent heat back into the process, drastically slashing fossil fuel consumption and advancing eco-friendly resource circularity.
MVR Application Fields
- 1 Vapor recompression downstream of high-temperature heat pumps for steam production
- 2 Vapor recompression for steaming and boiling processes in food and beverage plants
- 3 Compression of flash steam generated during industrial condensate recovery
- 4 Pressure boosting for process steam supply integration
- 5 Recompression of vent vapors in chemical plants and large manufacturing complexes
- 6 Low-temperature waste heat (60–70°C) recovery for clean industrial steam generation
